Left 4 Dead 2

Today in the morning, I was playing The Chapter : No Mercy(Versus),while I was very excited that My team was supposed to win! But something bad happened: I was switched to my enemies' team after loading, finally I was kicked by my team! What a pity to me! I lost my game! Sometimes I hear other players in L4D2 also complain a problem like what I've indicate,and I think Valve really has to fix this bug!

It is not a bug. The thing is, when people tend to lose, especially towards the end of the game, they know there is nothing they can do to win so they will grief. Basically, if they load faster than some people from your team, they will press M and switch teams to be on the winning team (your team). Therefore, as you are not loaded in yet, as you load in the game your spot will be taken by the idiot from the other team that has switched to yours. So you have no other place to go than the other team (his previous team)...and then they vote kick you (since they are probably griefers as well in cooperation with their teammate who switched to your team).

It happened to me as well many times. It happens to most good players who tend to win more often (obviously there is no need to switch and grief if your team is losing). I have adressed this issue here a couple of times to ask Valve to disable the team switching in mid game, or at least for the last 2 chapters of any campaign. Some people have said that it is not a good idea since they use that option to switch to the losing team or a team that lacks a player, to even the teams. However, I call bs on that one. Those kind of people are VERY rare, more like 1 in 100. And most people that use the switch team option, are the kind of people who want to ruin the game.

This is why I always tell my teammates (whenever we have a lead and are about to win a game) : be ready to kick any team switching griefer since there is a possibility that it will happen.

Some people switch, to make you go on their team and ruin the game that way. Some switch and shoot the whole team then disconnect/reconnect and go back to their previous team. Basically, it is impossible to prevent this from happening.
